Karl Bauer's popular book about Regensburg in history, art, culture, and customs is considered the standard work on the 2000-year-old Danube city. First published in 1962, it has been repeatedly revised, improved, and expanded, resulting in six editions with a total of 40,000 copies sold. The new edition has now been revised and expanded by his son, Peter Bauer. The author provides insights into almost every street, every historically interesting building, and every notable figure in Regensburg's history. It is a book for both leisurely reading and an indispensable reference work.
